UNITED STATES PATENT OFFICE.

WILLIAM B. OABLETON, or BOSTON, MASSACHUSETTS.

.BRICK.

SPECIFICATION forming part of Letters Patent' No. 293,716, dated February 19, 1884.

A Application filed December 27, 1883. (No model.)

To all whom, t may concern,.-

Be it known that I, WILLIAM E. CABLETON, of Boston, in the county ofrSuffolk and State of Massachusetts, have invented a new and useful Improvement in Bricks, of which the following is a full, clear, and exact descripf I air through Walls, and is anv improvement on the perforated brick patented to Louis Prince, May 22, 1883, No. 278,268.

My invention consists in forming a molding on the face'of the brick, a beading surrounding the slot or perforation, as herein explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In' the drawings, A represents a brick molded with the slot or perforation a through its center, to form an air-passage through awall,

as is fully described in the patent before referred to In the construction of walls built of these perforated brick, the soft mortar is apt to spread and run into the perforations, and consequently they may become closed u'p and defeat the object sought to be gained by the use of these bricks. Mortar is also liable to The Object of my present improvement is to overcome these difiiculties; and this I accomplish by molding the brick with a beading, B,

surrounding the slot or perforation, and rising above the face of the brick to about the distance it is proposed to separate the layers of bricks with mortar. It is evident that by means of this beading I accomplish two important results. First, I prevent the mortar from entering the slot by confining the mortar to the face of the brick outside of the beading, -whieh forms a guard-wall to the slot; and, secondly, I furnish a gage to the Workman by which he is enabled to keep his wall level, it being only necessary to see that each `layer of bricks is brought down flat upon the beading of the preceding layer, thus avoiding the usual loss of time and labor in leveling each course of bricks as the work progresses.

Having thus explained my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improved article of manufacture, a brick having a tapering slot or opening, a, and provided with a beading, B, surrounding the slot and raised above the face of the brick, substantially as and for the purpose herein set forth.
